  In the conventional method of sliding a finger on the touch panel, operating a pointing device or a rotation switch, or tilting the information browsing apparatus itself, a large operation is required for turning the page. For example, when sliding on the touch panel, the finger must be moved greatly, and when operating a specific operation unit such as a pointing device or a rotation switch, the finger must be moved to the operation unit, When tilting the device, the entire hand holding the device must be moved. For this reason, when the page is flipped, such a large operation must be repeated many times, which is inconvenient.

  In addition, regarding a method of sliding a finger on the touch panel, when the display unit is thin and easy to bend like electronic paper, or when the information browsing device is held and operated, the information browsing device is sandwiched (for example, Hold the information browsing device with your thumb and index finger). However, if the finger on the touch panel is slid greatly while holding the information browsing device, the information browsing device may be dropped. On the other hand, if the slide amount is reduced so as not to drop the information browsing device, it is difficult to accurately determine the page turning operation.

  In addition, regarding a method of operating a specific operation unit such as a pointing device or a rotary switch, a specific device including the specific operation unit must be used, and thus lacks versatility. In addition, regarding the method of tilting the information browsing device itself, when the size or weight of the information browsing device is large or when the information browsing device is operated on a desk or the like, the operation itself of tilting the device becomes difficult.

  The present invention has been made in view of the above problems, and its main object is to control the page turning display by instructing the page turning direction, speed, and number of sheets with a simple operation. An information browsing apparatus, a display control program, and a display control method are provided.

  In order to achieve the above object, the present invention provides an information browsing device including a display unit provided with a touch panel, and specifies a rotation direction and a rotation amount and / or a rotation speed of a finger or a hand that is in contact with the touch panel, The page turning direction is determined based on the rotation direction of the finger or the hand, and the page turning speed is determined based on the rotation amount and / or the rotation speed of the finger or the hand, and is currently displayed at the page turning speed. A display control unit that controls the display of page turning so that the current page is switched to the page specified based on the page turning direction.

  The present invention is also a page turning display control method in an information browsing apparatus including a display unit provided with a touch panel, wherein the rotation direction and rotation amount and / or rotation speed of a finger or hand touching the touch panel are calculated. A second step of determining a page turning direction based on a first step to be identified and a rotation direction and / or a rotation speed of the finger or hand based on a rotation direction and / or a rotation speed of the finger or hand; And a third step of controlling the display of page turning so that the currently displayed page is switched to the page specified based on the page turning direction at the page turning speed.

  According to the information browsing apparatus, the display control program, and the display control method of the present invention, it is possible to control the page turning display by instructing the page turning direction, speed, and number of sheets with a simple operation.

  The reason is that the information browsing device (display control program) acquires the shape of the contact portion when the finger or the like is brought into contact with the patch panel, and based on the change in the shape of the contact portion, the rotation direction of the finger or the like This is because the rotation amount and the rotation speed are specified, and the page turning direction, the rotation amount, and the rotation speed are determined based on the specified rotation direction, rotation amount, and rotation speed, and the page turning display is controlled.

  As shown in the background art, information browsing devices such as tablet terminals, electronic papers, and electronic books having a touch panel on a display unit have become widespread, and the number of users browsing documents such as materials and books has increased. As a method of turning a document page displayed on the information browsing device, a method of sliding a finger on a touch panel, operating a pointing device or a rotation switch, or tilting the information browsing device itself has been proposed. . However, these methods require a large operation when turning the page. Therefore, when flipping a page, the large operation must be repeated many times, which is inconvenient.

  Also, when operating with an information browsing device such as flexible electronic paper held in hand, to hold the information browsing device, in the method of sliding your finger on the touch panel, There is a risk of dropping the information browsing device, and if the slide amount is reduced, it becomes difficult to accurately determine the page turning operation.

  In addition, in a method of operating a specific operation unit such as a pointing device or a rotation switch, a specific device having a specific operation unit must be used. Therefore, the method of tilting the information browsing device itself is lacking in versatility. In an information browsing apparatus that is large in size and weight and is generally operated on a desk or the like, the operation of tilting the apparatus itself becomes difficult.

  Therefore, in one embodiment of the present invention, in order to reliably operate page turning with a simple operation, the direction and speed of page turning, the number of pages to be turned, etc. by rotating the finger or the like placed on the touch panel. We propose a new method of controlling Specifically, in an information browsing device that can acquire the shape of the contact portion when a finger or the like is touched on the touch panel, the rotation direction, rotation amount, and rotation speed of the finger or the like based on the change in the shape of the contact portion And turning the page displayed on the screen with the page turning direction according to the rotation direction, the page turning speed and the number of pages turned according to the rotation amount and the rotation speed.

  This makes it possible to operate page turning while intuitively changing the direction and speed of page turning and the number of pages to be turned, especially when operating with a flexible information browsing device such as electronic paper. Even if it exists, a desired page turning can be implement | achieved reliably and a user's convenience can be improved.

  In order to describe the above-described embodiment of the present invention in more detail, an information browsing apparatus, a display control program, and a display control method according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view schematically showing the appearance of the information browsing apparatus of the present embodiment, and FIG. 2 is a block diagram showing the configuration of the information browsing apparatus. FIG. 3 is a diagram for explaining the page turning operation by comparing the conventional method and the method of the present embodiment. FIG. 4 illustrates the conventional slide operation and the present embodiment with respect to the shape of the contact portion. It is a figure explaining comparing with rotation operation. FIG. 5 is a diagram showing another example of the rotation operation of the present embodiment, and FIGS. 6 to 9 are diagrams for explaining the page turning display method of the present embodiment. FIG. 10 is a flowchart showing a page turning process using the information browsing apparatus of this embodiment.

  In the following description, the operation of advancing a page is called page turning, the operation of moving back the page is called page returning, and the page turning and page returning are collectively called page turning. Further, the page turning in the information browsing apparatus is not limited to the operation of sequentially switching the displayed pages, but also includes the operation of moving a spread page when displaying a book or booklet that has been bound.

  As shown in FIG. 1, the information browsing apparatus 10 of a present Example is an apparatus provided with display functions, such as a notebook computer apparatus, a tablet terminal, electronic paper, an electronic book. As shown in FIG. 2, the information browsing apparatus 10 includes a CPU (Central Processing Unit) 11, a memory 12, a display unit 13, an operation unit (touch panel) 14, a communication unit 15, a battery 16, a page turning display control unit 17, and the like. Consists of.

  The CPU 11 executes a program read from the memory 12 and functions as a control unit that controls the operation of each unit.

  The memory 12 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Various programs that operate on the CPU 11 and setting information for controlling the operation of the information browsing device 10 (for example, a page turning display control unit). 17 stores a reference pattern for determining a change in the shape of the contact portion between the finger and the touch panel, various data (for example, document data), and the like. The memory 12 is also used as a counter for counting the number of pages turned.

  The display unit 13 includes electronic paper (EPD: Electrophoretic Display), a liquid crystal display (LCD), an organic EL (electroluminescence) display, and the like, and displays each page of a document based on document data. Electronic paper has a transparent conductive electrode formed on the inner surface of a pair of transparent film substrates, and a conductive black toner and an electrically insulating white toner are sealed between the electrodes, and a voltage is applied between the electrodes. When the toner is applied, the black toner moves and replaces the white toner to change the color.

  The operation unit 14 is a capacitive touch panel or the like in which transparent electrodes are arranged in a grid pattern on the front surface or the back surface of the display unit 13, and a signal output from the transparent electrode disposed in a portion touched by a finger or the like. Is sent to the CPU 11 and the page turning display control unit 17. In this embodiment, signals can be output from a plurality of transparent electrodes in a region touched with a finger or the like, and the shape of the region can be specified by processing the plurality of signals.

  The communication unit 15 includes a NIC (Network Interface Card), a modem, and the like, and communicates with a computer device or server connected to the network by wired communication or wireless communication, and receives document data and the like.

  The battery 16 is a secondary battery that supplies power for driving each unit of the information browsing apparatus 10.

  The page turning display control unit 17 acquires the shape of the contact portion when a finger or the like touches the touch panel based on the signal output from the operation unit 14, changes in the shape of the contact portion, and a previously stored pattern By comparing the rotation direction, rotation amount, and rotation speed of the finger, etc., determining the page turning direction according to the rotation direction, the page turning speed and the number of pages turned according to the rotation amount and rotation speed, The page turning operation displayed on the display unit 13 is controlled. The page turning display control unit 17 may be configured as hardware, or may be configured as a program (display control program) that causes the CPU 11 (control unit) to function as the page turning display control unit 17.

  Note that FIG. 2 is an example of the information browsing apparatus 10 of the present embodiment, and the configuration thereof can be appropriately changed as long as the page turning can be controlled based on the rotation operation of a finger or the like on the touch panel.

  Next, a page turning method will be described with reference to the schematic diagram of FIG. FIG. 3 is a diagram for explaining and comparing the page turning by the conventional sliding operation and the page turning by the rotation operation of the present embodiment.

  As shown in FIG. 3 (a), the conventional page turning by the slide operation is to move a finger or the like in a substantially constant direction with the finger placed on the touch panel, whereas FIG. 3 (b) shows. As described above, the page turning by the rotation operation of the present embodiment is to rotate the finger along the central axis in the longitudinal direction of the finger with the finger placed on the touch panel.

  As described above, the finger is slid on the touch panel in the past, and the finger is rotated on the touch panel in this embodiment, so the shape change of the contact portion where the fingertip is in contact with the touch panel The situation is different. Hereinafter, a specific description will be given with reference to FIG. FIG. 4 is a diagram illustrating a comparison between the change in the shape of the contact portion due to the conventional sliding operation and the change in the shape of the contact portion due to the rotation operation of this embodiment.

  As shown in FIG. 4A, in the conventional sliding operation, when the fingertip is brought into contact with the touch panel, the contact portion between the finger and the touch panel has a substantially constant size, and each has a similar shape. Further, since the positional relationship between the center point of the contact part and the finger is substantially constant, the center point of the contact part greatly moves in a constant direction in accordance with the movement of the finger.

  On the other hand, as shown in FIG. 4B, in the rotation operation of the present embodiment, the shape of the contact portion between the finger and the touch panel varies depending on the orientation of the contacted finger. For example, when touching the abdomen of a finger, the shape is almost rounded symmetrically, whereas when touching the side of the finger, it is asymmetrical (because the abdomen of the finger is softer) It becomes a long and slender shape. In addition, since the finger does not move much in the horizontal direction in the rotation operation, the amount of movement of the center point of the contact portion is smaller than that in the slide operation. The direction of movement is not constant.

  Thus, since the change in the shape of the contact portion, the amount of movement of the center point of the contact portion, and the movement direction are greatly different between the slide operation and the rotation operation, in this embodiment, paying attention to the shape change of the contact portion. Then, the shape change of the contact portion is compared with the previously stored pattern, and the page turning instruction associated with the pattern closest to the shape change of the contact portion is specified.

  More specifically, first, the pattern is created. For example, whether the fingertip is rotated clockwise or counterclockwise when viewed from the user side, the shape of the contact part is acquired based on the output signal of the touch panel at each time point, and the pattern is created by schematically changing the shape Alternatively, a pattern is created using an image creation application or the like. The pattern in the clockwise direction is associated with the page feed instruction, and the pattern in the counterclockwise direction is associated with the page return instruction. Thereafter, when a rotation operation is performed on the touch panel, it is determined which pattern the shape change of the contact portion is close to, and an instruction associated with the closest pattern is specified.

  In the above description, the shape change of the contact portion is applied to the pattern to determine whether it is a page feed instruction or a page return instruction. However, when the shape of the contact portion changes, the center of the contact portion If the point is moving to the right side as viewed from the user side, it may be determined to be a page feed instruction, and if it is moving to the left side, it may be determined to be a page return instruction.

  3 (b) and 4 (b) show the case where the fingertip is rotated about the longitudinal direction of the finger as the central axis, the rotation operation of this embodiment is performed by the contact portion that contacts the touch panel according to the rotation. For example, as shown in FIG. 5A, the entire hand may be rotated clockwise and counterclockwise as shown in FIG. 5A, or as shown in FIG. You may rotate to the direction which stands up (or the direction which lays down from the standing state).

  More specifically, as shown in FIG. 5A, when the entire hand (here, the right hand) is rotated clockwise as viewed from the user side, five fingers are in contact with the touch panel in the initial state. With the rotation, the touch panel moves away from the touch panel in the order of thumb, index finger, middle finger, and ring finger. Accordingly, when the shape changes so that the contact portion disappears in order from the left side when viewed from the user side from the state where there are five contact portions, it is determined that the contact has been rotated clockwise and the page feed instruction is determined. be able to. Similarly, when the entire hand (right hand) is rotated counterclockwise when viewed from the user side, the finger moves away from the touch panel in the order of little finger, ring finger, middle finger, and index finger. Therefore, when the shape changes so that the contact portion disappears in order from the right side when viewed from the user side from the state where there are five contact portions, it is determined that the rotation is counterclockwise and the instruction is for page return. can do.

  Further, even when the palm is in contact with the touch panel, it can be determined based on the shape change of the contact portion. For example, when the shape changes so that the contact portion gradually disappears from the left side when viewed from the user side, it can be determined that the rotation is clockwise and it is determined that the instruction is for page turning. Similarly, when the shape changes so that the contact portion gradually disappears from the right side when viewed from the user side, it can be determined that the rotation is counterclockwise, and the instruction is for page return.

  Further, as shown in FIG. 5B, when the finger is rotated in the direction in which the finger is raised, the contact portion is rounded because the finger belly is in contact with the touch panel in the initial state. It becomes an elongated shape horizontally. Therefore, when the shape changes in this way, it can be determined that the finger has been rotated in the direction in which the finger is raised, and it can be determined that the instruction is for page turning (or page returning). Similarly, when it is rotated in the direction in which it is laid down from a state where the finger is laid, it becomes an elongated shape in the initial state, but becomes a rounded shape with the rotation. Therefore, when the shape changes in this way, it can be determined that the finger has been rotated in the direction to lie down, and it can be determined that this is an instruction to return the page (or page forward).

  Hereinafter, a method for displaying a page when a page turning instruction is given by the above method will be described with reference to FIGS.

  FIG. 6 shows how the page changes depending on the rotation direction and rotation speed of the finger. For example, as shown in FIG. 6A, with the page (here, the second page) on the display unit 13 displayed, the fingertip is brought into contact with the touch panel and rotated clockwise as viewed from the user side. Then, the third page is displayed by determining that it is a page feed instruction. Also, as shown in FIG. 6B, when the fingertip is rotated counterclockwise while the second page is displayed, the first page is displayed based on a page return instruction. As shown in FIG. 6C, when the second page is displayed, if the fingertip is rotated fast or large clockwise, the page turning speed is increased or the number of pages turned is increased. Then, the fourth page is quickly displayed.

  FIG. 7 shows how a page is displayed by page turning or page returning. For example, as shown in FIG. 7A, when a page is instructed by rotating the fingertip clockwise as viewed from the user side in a state where a certain page (here, the first page) is displayed, The page may be displayed instantaneously, or as shown in FIG. 7B, the second page may be displayed after displaying the first page being gradually turned. At that time, the second page may be displayed in the portion where the first page is beaten, or nothing may be displayed.

  Further, when displaying a state in which the page is gradually turned, the place where the fingertip touches the touch panel may be specified and displayed so that the page is turned from a place close to the touched place. For example, in FIG. 7B, since the fingertip is in contact with the lower right corner of the page, it is displayed so as to be beaten from the lower right corner. In FIG. 7C, the fingertip is in contact with the upper right corner of the page. Therefore, it is displayed so as to be beaten from the upper right corner. Further, when the fingertip is in contact with the center of the side of the page, it may be displayed so as to be beaten from one corner of the side, or as shown in FIG. May be displayed so as to be gradually beaten.

  FIG. 8 shows a case where page feed (or page return) is continuously performed. As shown in FIG. 8, first, when a page (here, the first page) is displayed, the fingertip is brought into contact with the touch panel and rotated clockwise as viewed from the user side to instruct page turning. As described above, the second page is displayed. At that time, if the rotated fingertip is kept in contact with the touch panel, it is determined that the state in which the page feed is instructed continues and is constant. After the time has elapsed, the third page can be displayed. Then, when the page is sequentially sent and the tenth page is displayed, if the fingertip is rotated counterclockwise, it is determined that the instruction is to stop the page feed, and the display of the page can be continued. it can.

  When the fingertip is rotated counterclockwise, if the shape of the contact portion of the fingertip returns to the initial state (first page state), it is determined that the instruction is to stop page feed, and the counterpoint is further counter to the initial state. If it is rotated clockwise, it can be determined that the instruction is to return the page.

  6 to 8 show the case where the page is displayed in units of pages, but it is also possible to instruct page turning in the same manner in a state where a book or booklet is displayed. For example, as shown in FIG. 9A, with a book or booklet spread displayed, a fingertip is brought into contact with a certain page (here, page 9) and rotated clockwise as viewed from the user side. In this case, it is possible to control to display the tenth page and the eleventh page based on the instruction for page turning. Similarly, when the fingertip is brought into contact with the eighth page and rotated counterclockwise as viewed from the user side, it is determined to be a page return instruction, and control is performed so that the sixth page and the seventh page are displayed. You can also.

  If the fingertip is rotated clockwise on the 8th page or the fingertip is rotated counterclockwise on the 9th page, the page may be turned in the same manner, or the page may be left as it is. Good. It is also possible to determine that the rotation operation on the left page is a page return instruction regardless of the rotation direction, and the rotation operation on the right page can be determined to be a page feed instruction regardless of the rotation direction. .

  In addition, as shown in FIG. 9B, when the fore edge of the book or booklet is displayed (the surface opposite to the bound surface), the fingertip is brought into contact with the fore edge. You may control so that a corresponding page (here 10th page) is displayed. Further, it may be controlled to continue page turning according to the rotation direction of the fingertip (here, since it is a clockwise rotation as viewed from the user side).

  Hereinafter, a specific operation of the information browsing apparatus 10 (page turning display control unit 17) will be described with reference to a flowchart of FIG. In addition, since the conventional slide operation and the rotation operation of the present embodiment can be combined in page turning, FIG. 10 illustrates a case where the rotation operation of the present embodiment is performed in addition to the conventional slide operation. In the following description, it is assumed that the touch panel can recognize a plurality of points (has a so-called multi-touch function).

  First, based on the output from the operation unit 14, it is determined whether a finger has been placed on the touch panel (S101). If it is determined that a finger has been placed, it is determined how many fingers have been placed (S102). . If there are multiple fingers (usually two), either a pinch motion (a motion to widen or narrow the distance between fingers) or a rotation motion (rotate around the point between the two fingers) (S103). In the case of the pinch operation, the displayed image is enlarged / reduced according to the finger interval, and in the case of the rotation operation, the displayed image is rotated according to the rotation angle (S104), and the process returns to S101.

  On the other hand, when there is one finger placed, or when there are a plurality of placed fingers and neither a pinch action nor a rotation action (No in S103), a slide action (an action to move the finger in a substantially constant direction) ) Is determined (S105), and when the slide operation is performed, the finger moving direction is obtained from the coordinates of each position of the finger, and the moving speed of the finger is determined from the coordinates and time of each position of the finger. And the movement acceleration is obtained (S106). Then, the page turning direction is determined based on the moving direction of the finger, the page turning speed and the page turning number are determined based on the moving speed and the moving acceleration, and the page turning direction and speed are displayed on the display unit 13. The page specified by the number of pages is displayed (S107).

  The operation so far is the same as the conventional one, but the present embodiment is characterized in that the following processing is performed when the slide operation is not performed in S105.

  First, based on the output of the touch panel, it is determined whether or not a rotation operation for rotating the fingertip about the longitudinal direction of the finger as a central axis has been performed (whether the shape of the contact portion has changed) (S108). In addition, as shown in FIG. 5, you may perform the operation | movement which rotates the whole hand, and you may perform the operation | movement which raises a finger | toe (or puts the raised finger to sleep).

  If the rotation operation is not performed, the process returns to S101 and the same processing is repeated. If the rotation operation is performed, the rotation direction of the finger is compared by comparing the shape change of the contact portion with the previously stored pattern. Then, the rotation amount is obtained, and the rotation speed is obtained based on the contact time (S109). Then, the page turning direction (whether page turning or page returning) is determined based on the rotation direction of the finger. Further, the page turning number is determined based on the rotation amount of the finger, and the page turning speed is determined based on the rotation speed of the finger. Then, the page turning number is set in the counter of the memory 12 (S110).

  Here, the page turning number is determined based on the rotation amount of the finger, and the page turning speed is determined based on the rotation speed of the finger. However, only one of the page turning number or the page turning speed is determined. Alternatively, the page turning number may be determined based on the finger rotation speed, and the page turning speed may be determined based on the finger rotation amount.

  Next, in accordance with the determined page turning direction, speed, and number of pages to be turned, a predetermined page (the next page in the case of page feed and the previous page in the case of page return) is displayed on the display unit 13. Then, the page turning display control unit 17 subtracts 1 from the counter of the memory 12 (S111).

  Next, based on the output of the touch panel, it is determined whether the rotation operation of the finger or hand has changed (whether the shape of the contact portion has changed) (S112). If the rotation operation has not changed, it is determined whether the page turning operation for the predetermined number of pages determined in S110 has been completed (S114). If not, the process returns to S111 to repeat the page turning operation. When the page turning operation for a predetermined number of pages is completed, the page turning operation is stopped, the counter of the memory 12 is reset (S115), and the process returns to S101.

  On the other hand, if it is determined in S112 that the rotation has been further performed, the rotation amount is obtained, the number of pages turned according to the rotation amount is determined, and the number is added to the counter (S113). Then, it is determined whether the page turning operation for a predetermined number of pages has been completed (S114). If it has not been completed, the process returns to S111 to repeat the page turning operation, and if it has been completed, the page turning operation is stopped. The counter of the memory 12 is reset (S115), and the process returns to S101.

  If it is determined in S112 that the reverse rotation has occurred as shown in FIG. 8, the page turning operation is stopped, the counter of the memory 12 is reset (S115), and the process returns to S101.

  As described above, in this embodiment, the rotation direction, rotation amount, and rotation speed of the finger or hand are obtained based on the change in the shape of the contact portion when the finger or hand is rotated on the touch panel, and the page is determined from the rotation direction. Since the page turning speed and the number of page turning are determined from the turning direction (page feed or page return), the rotation speed and the rotation amount, the page turning can be instructed easily without moving the finger largely like the slide operation. .

  In addition, in the case of rotating operation, it can be operated even when the display unit is sandwiched between fingers, so even when the display unit is thin like electronic paper or when it is operated while being held by hand, it is safe and reliable. The page turning can be instructed.

  In addition, this invention is not limited to description of the said Example, As long as it does not deviate from the meaning of this invention, the structure and control can be changed suitably.

  For example, in the above embodiment, the page turning display is controlled based on the shape change of the contact portion when one or a plurality of fingertips or palms are brought into contact with the touch panel, but the part to be brought into contact with the touch panel is not limited to the above. For example, even when the entire finger is brought into contact, such as from the base of the thumb to the tip, or the side of the hand on the little finger side is brought into contact, the page turning display can be controlled similarly.

  The present invention can be used for an apparatus including a display unit provided with a touch panel, a program operating on the apparatus, and a method for controlling page turning display.
